SPECIFICATION formingpart of Letters Patent No. 729,419, tat-ed m 26,1903. Application filed November 12,1902. SerialNo.131,059. (Home Be itknown that I, BYRD G."RooKWELL, a;

citizen of the United States, residing at Perla,

in the countyof Hot Springs and State of Arkansas, have invented a newand useful Adjustable Window-Screen, of which the following is aspecification.

This invention relates to adjustable win- (low-screens. V

The object of the invention is in a ready, simple, thoroughly feasible,and practical manner and .without materially weakening the frame-bars bysimply removing there from a trifling amount of material to associ-' atethe said bars in such manner as to per mit of their being readilylengthened or short- 1 ened, as desired,-.to-improve the manner ofconnecting the frame-bars for the purpose stated,to improve the mannerof connecting the screen with the stile, to provide a novel form of stopfor limiting the extension of the sections, and generally to improvethis class of window-screens.

With these and other objects in. view, as will appear as the nature ofthe invention is better understood, the same consists in the novelconstruction and combination of parts of an adjustable window-screen, aswill be hereinafter. fully. described and claimed.

In the accompanying drawings, forming a part of this specification,andin'which like characters of reference indicate corresponding parts,there is illustrated one form of the invention capable of carrying thesame into practical operation, it being understood that the elementstherein exhibited maybe varied or changed as to shape, proportion, andex-' act manner of assemblage without departing from the spirit thereof,and in the drawings- Figure 1 is a view in elevation of one member of awindow-screen constructed in accordance with this invention. Fig. 2 is aiew invertical transverse section, showing the'mannor of connectingthetwo screen-members. Fig. 3 is a view in longitudinal section, taken onthe line 3 3 of Fig. 1. Fig. 4 is a perspective detail View showing theimproved manner'of associating the frame-bars and the stile, and Fig. 5is a perspective detail view of the clip that holds the screen membersconnected.

As each of the screen-sections is a counterpart of the other, adescription of one will serve for both. Each frame-section comprises astile 1 and two framebars 2 and 3.

vAs above stated, one of the essential features of the present inventionresides in the manner. in which the screen is secured to the stile, theobject being to avoid the employment of the ordinary cap or batten onthe improved manner of securing the end of the screen to the stileinvolves a radical change in the construction of the stile,w'hich alsoconstitutes one of thefeatures of novelty of the present inventiom Inwindow-screens of this character in ordinary use the "stile is composedof a stripof wood, to which the framebars and screen are secured, and acap or backing secured to thestile tocover the attached portion of thescreen. This necessitates the employment of two sticks of wood and theirassemblage and of necessity makes the stile somewhat heavy. With thestile of the present invention its ends are mortised at 4 to receive thet'enons 5 of the frame-bars,

.and the inner edge of one side'of the stile is provided with a rabbet 6to receive a batten 7, which operates to secure one end of the screen 8to the stile. The manner in which this is effected is shown in Fig. 3and is acstile to cover the end of the screen, and the complished byfirst disposing-the end of the I the screen over the batten and securingit along its edges in rabbets9 and 10, formed in one side of the inneredges of the framebars, as clearly shown in Figs. 1 and 2. n It will beseen by employing a stile with mortised ends, as described, incombination with frame-bars having tenoned endsand. by providing thestile with the rabbet 6 to receive the batten 7 that the employment ofthe ordinary cap in common use will be obviated, thereby not onlyreducing the cost of production of the article, but also making itlighter and giving it a more finished appearance.

Another portion of the invention resides in the peculiar manner ofassembling the binding 11 of the screen to the frame-bars in such manneras to cause the attaching means employed for the purpose to constitutestops to limit the extension of the screen-sections. This is efl'ectedby the employment of staples 2, which straddle the binding, as clearlyshown in Fig. 1, and extend a sufficient distance above the binding toengage with the opposite section, and thus perform the functiondesigned.

Another portion of the invention resides in the peculiar manner ofassociating the screen-sections for opening and closing withoutmaterially sacrificing stock or weakening the frame-bars. This isetfected by providing the opposed faces of the frame-bars each with twosaw-kerfs 13 and 14, which diverge and which when the frame-bars arejuxtaposed, as shown in Fig. 2, present X-shaped guides or grooves. Themeans employed for holding the frame-sections assembled for adjustablemovement with relation to each other consists of metallic clips, one ofwhich is shown in detail in Fig. 5 and comprises a sheet-metal structureconsisting of a body portion 15, having terminal downturnedoutward-divergent securing members 15 and intermediate upward andoutwardly-divergent flanges 16, constituting guide members. The lattermembers are somewhat shorter than the depth of the saw-kerfs and arepitched. at an angle corresponding thereto; but the securing tnetnbers15' are normally disposed at a greater distance apart than the membersof the kerfs, so that when forced therein, as' shown in Fig. 2, theywill effect a secure assemblage of the clip to the frame-bar. It is tobe understood. that each terminal of the? frame members will be providedwith one of these clips to engage with the kerfs of the frame-bars ofthe other member, and as the guide members work loosely in the kerfs anydanger of binding or locking of the parts in use will be reduced to aminimum. In fact,

the guide members may be so bent initially' as positively to obviatethis danger.

A window-screen constructed in accordance with this invention is light,strong, and durable and by reason of the manner of construction andassociation of its parts will be found to be thoroughly eflfective forlong service without dangerof derangement of its parts,

Having thus described the invention, what I claim is 1. In an adjustablescreen, a stile having a rabbet disposed adjacent to its inner edge, ascreen having one end disposed within the rabbet, and a batten securedin the rabbet and clamping the screen therein, the screen being turnedover upon the batten and then secured to the side bars of the frame.

2. In an adjustable screen, a screen-section comprising frame-bars eachhaving one end provided with a tenon, a stile having its ends mortisedto receive the tenons and provided along its inner edge with a rabbet, ascreen having one end seated in the rabbet, a batten secured within therabbet and clamping the end of the screen therein, the screen beingturned over upon the batten and then secured along its edges to theframe-bars.

3. In an adjustable screen, the combination with the screen-binding andframe-bars, of means for securing the ends of the binding to theframe-bars, said securing means constituting stops to limit theextension of the screen-sections.

4. In an adjustable screen, the combination with twolongitudinally-adjustable framebars provided with oppositely divergingkerfs, of a clip having oppositely-disposed members adapted to engagethe kerfs in the bars for slidingly connecting the same, the engagingmembers being formed by slitting the clip-blank inward transversely fromits edges to form a plurality of longitudinallydisposed edge sectionsand bending said sections laterally in opposite directions;.

In testimony that I claim the foregoing as my own I have hereto ain'xedmy signature in the presence of two witnesses.
